ACCESSORY FOR USE WITH TELEPHONES Filed May 25, 1949 3 Sheets-Sheet 3INVENTOR SANFORD C. CHESICK By ,1 gjrv wav TORNEY Vertically movable onthe post 14 is a slide 34 which is preferably in the form of a sleevesurrounding and fitting the post. Carried by the slide or sleeve 34 is ahorizontally extending arm 36 which extends over the button 32 as shownin Fig. 1. Preferably the sleeve 34 is guided for vertical movement onthe post 14, relative rotative movement being prevented by a pin 38extending into a vertical spline 40, as shown in Fig. 3. Thus the sleeve34 is free for vertical movement, but relative rotative movement isprevented.

Preferably the arm 36 is rotatively connected with the sleeve 34, thisbeing desirable in order that the telephone base may be placed indifferent positions on the platform 10. As shown, the arm has anaperture through which the sleeve extends, the sleeve having an externalthread 42 and the aperture in the arm having a mating internal thread.The mating threads permit the arm to be turned relatively to the sleeve.

For vertically moving the sleeve 34 and the arm 36 there is provided atleast one manually movable eccentric and preferably there are two sucheccentrics. As shown, the post 14 is flattened at opposite sides and arotatable shaft 44 extends through a horizontal bearing aperture in thepost. Secured to the shaft 44 are two similar eccentrics 46, 46 whichengage the opposite fiat faces of the post. Connected with the shaft 44and the eccentrics 46, 46 is a manually operable lever 48 for turningthe said shaft and eccentrics. When the lever 48 is in the upperposition, as shown in Figs. 1, 2 and 3, the eccentrics are in thepositions to permit the sleeve 34 and the arm 36 to move to theirlowermost positions. When the lever 48 is moved to its lowermostposition, the eccentrics 46, 46 move the sleeve 34 and the arm 36 totheir uppermost positions. Inasmuch as there are two eccentrics,pressure is applied to the sleeve 34 at both sides of the post. A pin 50on the post 14 limits the movement of the lever 48 so that the sleeve 34and the arm 36 are either in their lowermost positions or in theiruppermost positions. Preferably the lever 48 has notches as shown toreceive the pin 50 A spring is preferably provided for biasing thesleeve 34 and the arm 36 in the downward direction and as shown there isa coil spring 52 which surrounds the upper portion of the post 14. Thelower end of the spring 52 abuts against the top of the sleeve 34 andthe upper end of the spring abuts against a sleeve 54 carried by theupper portion of the post.

As has been stated, the arm 36 engages the button 32 on the base of thetelephone. When the lever 48 is moved to its upper position, as shown,the arm 36 is moved downward by gravity and by the spring 52 so as todepress the button 32 to its lower open-circuit position. When the lever48 is moved to its lower position, the sleeve 34 and the arm 36 aremoved upward thus permitting the button 32 to assume its upperclosedcircuit position. Thus the user of the accessory can close or openthe telephone circuit at will by merely moving the lever 48.

The base of the telephone has the usual upward projections 56, 56 atopposite sides of the button 32 and preferably the arm 36 is providedwith two pairs of rollers 58, 58 which are so positioned that therollers of the said pairs are at opposite sides of the said projections56, 56. The rollers are preferably formed at least in part of rubber orequivalent material. The telephone base 30 is accurately positioned onthe platform so that the projections 56, 56 thereof are between thepairs of rollers 58, 58. The rollers constitute anti-friction meanswhich permit the arm 36 to freely move upward or downward with respectto the base and inasmuch as the said rollers are formed at least in partof rubber or equivalent material, there is no possibility of scratchingthe said projections on the base.

The telephone base shown in Figs. 1 and 2 is that of a standardtelephone. Certain other telephones, as for instance those forinter-office use, have the button 32 at a slightly different elevation.In order to properly cooperate with buttons at different elevations, thearm 36 is vertically adjustable with respect to the sleeve 34. Thebefore-mentioned threaded connection between the arm and the sleeve isutilized for vertical adjustment. The arm 36 can be turned in eitherdirection on the threads and can be thus raised or lowered. The fulllines in Fig. 3 show the arm in a lower position and the dotted linesshow it in an upper position. For locking the arm 36 in adjustedposition there is provided a threaded sleeve all) 60 which serves as alock nut. The sleeve 60 is in-- ternally threaded to engage the threadon the sleeve 34 and the lower end of the sleeve 60 abuts against thearm 36. The sleeve 60 is of such length that it encloses the spring 52,the upper end of the sleeve fitting the sleeve 54. The sleeve 69 ispreferably exteriorly knurled so that it may be readily turned into orout of locking engagement with the arm 36.

The upper portion of the post 14 has a central cylindrical aperturetherein and a vertical rod 62 accurately fits this aperture. The rod 62is rotatable in the aperture and its lower end is seated against thebottom of the aperture. A laterally extending arm 64 is provided whichis adjustably connected with the upper portion of the rod 62.

For connecting the arm 64 with the rod 62 there is provided a block 66apertured at the bottom to receive the upper end of the rod. The blockis preferably pinned to the rod. The block 66 has a central recess atthe top, this recess providing two cars 68, 68 at the sides. Aninterrupted horizontal bearing aperture is formed in the cars 68, 63,this bearing aperture receiving and fitting a horizontal trunnion pin 70which is pivotally movable in the aperture. The corresponding endportion of the arm 64 is reduced in diameter and extends through acentral aperture in the trunnion pin 76. The arm 64 is permanentlysecured in its position in the pin. It will be seen that the arm 64 canbe moved in a vertical plane about the axis of the pin 70.

The block 66 has a diagonal slot as indicated at 72, this slot extendingto the aperture for the pin 70. A screw 74 extends through a horizontalhole in the block, the said hole intersecting the slot 72. Positioned atthe right side of the block 66 is a sleeve 76 surrounding the screw andhaving a flange 78 adjacent the block. A disc 80 is rotatably mounted onthe sleeve 76 adjacent the flange 78. Surrounding the sleeve 76 is asleeve 82 closely adjacent the disc 80. At its outer end the sleeve 82has an end wall with a hole into which the end of the screw 74 extends.The end of the screw is enlarged so that the sleeve 82 cannot moveendwise with respect to the screw. A coil spring 84 is located betweenthe sleeves '76 and 82, one end abutting against the disc 80 and theother end abutting against the end wall of the sleeve 82. At itsopposite end the screw is provided r with a knurled head 86 by means ofwhich it may be turned.

The screw 74 has threaded engagement with the block 66 at the right ofthe slot 72, but does not have threaded engagement with the remainder ofthe block nor with the sleeve 76. When the screw 74 is turned in onedirection the two portions of the block 66 at opposite sides of the slot'72 are forced toward each other so as to grip the pin 70 and prevent itfrom turning. Thus the arm 64 can be clamped in adjusted positions. Whenthe screw is turned in the opposite direction the pin 70 and the arm 64are released.

The disc 80 is provided at its periphery with a series of notches 88which have successively increasing depths and each of which is of suchwidth as to receive the reduced end portion of the arm 64. Eight notchesare shown but the number may be varied. The arm 64 may be held in anelevated adjusted position solely by the clamping action on the trunnionpin 79. However, when the arm 64 is in a lower adjusted position, thereduced end portion thereof is entered in one of the notches 88 so as tobe positively supported. When the pin 70 and the disc 80 are released,the arm 64 may be moved temporarily to an elevated position and the disc80 may be turned to bring any selected notch 88 into register with thereduced end portion of the arm. The spring 84 provides frictionalresistance to prevent free turning of the disc 80. The arm 64 may belowered into the selected notch, and then the screw 74 is turned toclamp the pin 70 and the arm 64. Thus the arm 64 may be positivelysupported in any one of eight different positions.

The holder 26 is preferably carried by a plate 90 which is so connectedwith the arm 64 that it may be rotatably adjusted with respect thereto.As shown in Figs. 7 and 8, there is provided a disc 92 havin a hollowhub 94 which is interiorly threaded for engagement with a threaded endportion of the arm 64. A second disc 96 is provided which normally hasface to face engagement with the disc 92, the said disc 96 beingdirectly connected with the plate 90. The disc 96 is provided with anintegral stud 98 which extends through an aperture in the disc 92 andinto the hollow hub 94 thereof. A coil commay be connected with theplate in any one of a plurality of different angular positions withrespect to an axis perpendicular to the plate. Between the rear wall 116and the head 143 the stud 146 has a polygonal shape at 149, which shapeis preferably a hexagon. The opposite parallel walls of the stud at 149are so spaced as to be adapted to enter between and approximately fitthe side walls of the slot 142 as shown in Fig. 15. The head 148 of thestud or retainer is of such size as to be adapted to pass through theopening 144 in the plate 140.

Preferably the upper portion of the plate 140 having the opening 144therein is somewhat thinner than the lower portion of the said plate.The thickness of the upper portion of the plate is somewhat less thanthe distance between the holder wall 116 and the adjacent face of thehead 148. This facilitates entry of the stud or retainer so that thehead 148 thereof will freely pass behind the face of the plate when theholder and stud are moved downward. 'lhe lower portion of the plate 140is thicker, its thickness being approximately the same as the distancebetween the holder wall 116 and the adjacent face of the head 148. Thus,when the holder and stud are in their normal lower position, the holderis firmly connected with the plate without any lost motion. Thethickness of the plate may be made increasingly greater at steps v, 151and 152 as shown in Fig. 15.

When the shape at 149 is hexagonal the holder 26 can be connected withthe plate 140 in a plurality of positions which are angularly different,the several optional positions being at 60 from each other. Thedescribed construction not only enables the holder to be attached to theplate at a variety of angularly different positions but also enables theholder to be readily detached from the plate 140 by manually moving itparallelly with the said plate. in order to detach the holder it ismerely necessary to move it along the plate and to then raise it so thatthe head 148 can be moved through the opening 144. Fig. 14 shows theholder detached from the plate.

Fig. 18 shows a construction similar to that shown in Figs. 13 to 17 butdifferent in detail. In lieu of the stud 146 there is provided a stud153 having a head 154 similar to the head 143. Between the wall 116 andthe head 154 the stud 153 is threaded and a nut 155 is engaged with thethreaded portion of the stud. The thickness of the nut 155 is slightlyless than the distance between the wall 116 and the head 154. Theexterior shape of the nut 155 is or may be the same as the exteriorshape of the stud 146 at 149. The construction shown in Fig. 18 servesthe same purpose as the construction shown in Figs. 15 to 17. The holder26 can be put in place in any one of several angularly differentpositions and the holder can be readily removed and replaced asrequired.

The thickness of the nut 155 is only a few thousandths of an inch lessthan the distance between the wall 116 and the head 154 and the nut 155is rotatable with respect to the stud through only a small fraction of aturn. With the holder 26 in place on the plate 140, it can be rotatedthrough the aforesaid small fraction of a turn, preferably less than 60.When the holder is rotated in one direction, one face of the nut isbrought into engagement with the head 154 as shown in Fig. 18, theholder being thus frictionally locked. When the holder is rotated in theother direction, the opposite face of the nut is brought into engagementwith the wall 116, the holder being again frictionally locked. With theconstruction shown in Fig.

18 the holder 26 can be rotated and frictionally locked at intermediatepositions between the positions determined by the engagement of theopposite sides of the nut 155 with the walls of the slot 142.

Fig. 18 shows a construction similar to that illus-- trated in Fig. 18but differing in detail. There is a stud 153 which is or may be the sameas the stud shown in Fig. 18, the said stud having a similar head 154.in lieu of the nut 155 there is provided a nut 156 which is similar tothe nut 155 but somewhat thinner. sides of the nut 156 are twooppositely disposed dished spring washers 157, 157. The angle of thewashers is considerably exaggerated in the drawing for clarity ofillustration. In practice the angle is very small and the nut 156 has athickness considerably greater than that shown. The action is the sameas that described in connection with Fig. 18 except that the washersfrictionally resist rotative movement of the nut and thus resistrotative movement of the holder. When the nut 156 moves toward the head154 one washer is flattened and,

At oppositewhen the nut moves toward the wall 116 the other Washer isflattened.

Figs. 19 to 24 show another alternative construction for connecting theholder with its supporting plate and for enabling the holder to beangularly adjusted. A supporting plate 158 is provided generally similarin function to the supporting plate 90. in lieu of the arm 64, an arm160 is provided which is generally similar to the arm 64 but which isrigidly connected with the plate 158 instead of being connectedtherewith by means of a mechanism such as that shown in Figs. 7 and 8.

Secured to the plate 158 are two oppositely positioned gibs 162, 162which constitute a guide extending parallelly with the plate 158. Thesaid gibs engage with and support a slide or retainer 164 connected withthe holder 26. The slide or retainer 164 has lateral projections 166,166 at the top which engage the gibs to limit downward movement of theslide. lnasmuch as the holder 26 is secured to the slide 164, the holderis thus supported on the plate 158. it will be seen that the holder 26can be detached from the plate 158 by merely moving the said holder andthe slide or retainer upward parallelly with the plate so that the slideis disengaged from the gibs or guide. Fig. 23 shows the holder andretainer detached from the plate.

Preferably the holder 26 is connected with the slide or retainer 164 forangular adjustment with respect thereto. As shown, a washer 168 issecured to the rear wall 116 of the holder, this washer engaging at itsrear with the front face of the slide 164. A rivet 171) extends throughsuitable apertures in the wall 116, in the washer 168 and in the slide164. It will be seen that the holder 26 and the washer 168 can beangularly adjusted with respect to the slide 164 about the axis of therivet 170. A spring washer 172 is interposed between the wall 116 andone head of the rivet 170, this spring washer providing frictionalengagement between the washer 168 and the slide 164. Preferably thewasher 168 has an annular series of detents 174 which are adapted toenter a similar series of depressions 176, 176 in the front of the slide164. With the detents entered in the depressions the washer 168 and theholder 26 are yieldably held in any one of a plurality of angularlydifferent positions.
